The Aqara Door and Window Sensor pairs with an Aqara hub over Zigbee. The Ecobee SmartSensor for Doors & Windows connects over 2.4 GHz Wi-Fi but its Google Home, Alexa and Apple Home links go through an ecobee thermostat, so it only makes sense in an ecobee home.
The Ecobee adds an occupancy sensor with a 120 degree view, so the thermostat knows when someone walks past the door. The Aqara reports open and close only. The Ecobee's motion alerts, though, need a subscription.
Aqara reaches Apple Home, Google Home, Alexa and Home Assistant, and through its hub also Matter and SmartThings. The Ecobee has no Home Assistant, SmartThings or Matter support, which rules it out for most DIY setups.
The Ecobee's CR2477 is rated for 3 years and the Aqara's CR1632 for 2, and the Ecobee carries a 3 year warranty against 1 year. Both are long enough that battery swaps are a rare chore either way.
At 41 x 22 x 11 mm, the Aqara is far smaller than the 60 x 29 x 21 mm Ecobee, which matters on narrow window frames.
The Ecobee SmartSensor for Doors & Windows pairs directly with the thermostat and pauses heating or cooling when a window is left open.
The Aqara Door and Window Sensor is supported there, while the Ecobee has no Home Assistant integration.
Its open, close and tamper alerts come through the Aqara hub, while most Ecobee security features require ecobee Smart Security.
The Ecobee carries an occupancy sensor that feeds the thermostat, which the Aqara does not have.
Owners of both are happy with how fast the sensors report and how easy they are to stick up, and neither group sees them as standalone. Aqara Door and Window Sensor owners single out the tiny size and long coin cell life, and use it widely in Apple Home, Alexa and Home Assistant automations; their complaint is that it wants an Aqara hub and can lock up on mixed Home Assistant Zigbee networks. Ecobee SmartSensor for Doors & Windows owners love one thing above all, the thermostat turning off heating or cooling when a door or window is left open. Their dominant complaint is that motion, arming and occupancy alerts sit behind an ecobee Smart Security subscription, and they also note the Alexa and Google links are limited to arming and that the sensor does not measure temperature.
The Ecobee SmartSensor for Doors & Windows wins on warranty, battery life and its built-in occupancy sensor, which makes it the better choice with an ecobee thermostat. The Aqara Door and Window Sensor is better for anyone outside the ecobee ecosystem, with support for Apple Home, Google Home, Alexa and Home Assistant.
Yes. The Ecobee SmartSensor for Doors & Windows works through an ecobee thermostat, and its Google Home, Alexa and Apple Home links depend on it. The Aqara Door and Window Sensor needs an Aqara hub instead.
The Aqara Door and Window Sensor does. The Ecobee SmartSensor for Doors & Windows does not: the Home Assistant ecobee integration covers thermostats and their room sensors, not these door and window sensors.
Open and close notifications and pausing the thermostat work without one, but motion alerts and most security features need an ecobee Smart Security subscription. The Aqara Door and Window Sensor has no subscription.
Anyone building a general smart home around Apple Home, Google Home, Alexa or Home Assistant who wants a tiny contact sensor with tamper alerts through an Aqara hub.
Ecobee thermostat owners who want heating and cooling to pause when a door or window is left open, and who value its occupancy sensing and 3 year warranty.
